Dave Lindsay: At which time I'll just disable antenna power. Being 3 miles from the mast, I shouldn't have needed to do it in the first place.
Kevin Hodges: All should be up to 100KW next June, we're just being fobbed off with a paltry 2.2KW for some channels now until June 27th

Thanks Aaron, It's strange that some of you guys are having these problems, I'm in CM2 (which actually shows as outside the best reception on the map above) and receive all Mux's via a loft aerial. Just hope I don't regret saying that!

I'm in Braintree.
Back in July I was very happy with lovely signal strength and picture quality on all my Freeview Channels following the Digital Switchover - so I know there's nothing wrong with my kit - since November this year Film 4 and ITV 4 to name a couple are now mostly unwatchable (they went briefly altogether fo a few days. Something clearly happened but what - could someone please explain it to me and explain who I talk to or what I have to do to get my July quality of service back?
I don't recall anyone warning of any changes to the service beyond those of the July switchover so, in reading these pasts, if they have changed something surely reducing the quality of service is something that OFCOM would never allow?

Neil, in November, as part of the switchover for Tacolneston transmitter (the next one North of Sudbury) the carrier on Sudbury for Film4 etc. was moved to a higher frequency. This frequency, is difficult to receive for many aerials and receivers and, just to put the tin lid on it, the power is also very low. The reason that the power is low is so that it doesn't interfere with the Dover area.
Once Dover have finished their switchover, on 27th June 2012, a different frequency will be allocated which is both easier to receive and the power will go up to the full level.
So, you have a quandry - either put up with missing channels for the next 6 months, or invest money in upgrading your system, despite the fact that you've probably already had to do that once already.

Steve Ilott: I Must agree with david popperwell's comments. I live in the Clacton on sea area and after returning form holiday last week find that I have lost all freeview channels broadcast on band '50' i.e. Film4, Yesterday, ITV4 etc. Rang up the digital switchover people and was told that the Sudbury transmitter had technical issues Nov 17th (I think it was) and service had changed to channel 63 which I would need a new (band e) aerial for. My other option is to wait until 27 June when it will be fixed apparently.

Are the mux/channel allocations right on page Freeview on Sudbury TV transmitter | ukfree.tv - independent free digital TV advice ?
We have a lot of comments about poor quality on 63 but it does not appear in the Freview Muxes list.

Think you're correct Vernon, it was on C50 until the last change. I'm sure the site administrators will note this and update when they have time. There's probably loads of changes happening at the moment and won't settle down until mid 2012, then we can all enjoy perfect Freeview! In the meantime you can always double check the channel numbers on the digitaluk site
